n. A commitment phobic playa (def. 2), specifically one who suckers a Lisa into thinking he is into them by hanging out with them all day (typically on weekdays since he’s often a scrubdef. 1). He may get the girl to pay for stuff based on some hard luck story (for example, his car was towed) and then never calls or offers to return the favor. A sachin’, however, will do things to continue to make it seem like he’s interested, but nothing that could smack of commitment. For example, a sachin’ will hang on to a piece of clothing as a means of forcing the woman to schedule another meeting to reclaim her stuff or call on New Year’s Day to say hi and tell her what a great time he had NYE.

Girl 1: Hey, did you ever get your hat back?
Girl 2: Yeah, and then he gave me a card. What do you think?
Girl 1: I think he's a sachin’ -- don't fall for it.
OR
He’s such a sachin’.

A Sachin refers to someone, not unlike a Piranavan, who has lost all contact with his school-friends as soon as it became inconvenient for them to contact him. This person will almost definitely plan an outing in December for his former-friends but will be stood up by all of them, because they have all moved on. Once, perhaps, he had friends, but none of them thought he was worth e-mailing more than once after he left. The Sachin is then only a punchline for over-recycled quips about the socially-retarded.

Liam: Yo homie, did you meet up with Sachin in December?
Jerrell: Who? Whatever, yo. I got better shit to think about.

- Somewhere in Central London -

Sachin: Oh, bitter taste of mine own medicine! And for all those yester-years whereupon I had accused lone Pran of romancing with Kanto, I have now fallen to his depth and beyond. But still, I wait, with utmost patience, upon the arrival of mine olde companions so that we may reunite in Central London and speak of Virtua Tennis and Fifa.
